light energy has been considered as one of promising renewable energy source
because it is clean, sustainable, abundant, and infinite. Therefore, extensive
studies have been done and as a result, the silicon based solar cells have been
widely used for power generation to date. However, it is still challenging to
develop more cost-effective high-efficiency solar cells to compete with
conventional fossil fuels because the additional reduce of processing cost in
silicon solar cells seems very difficult. Hence, the second generation solar
cells such as organic photovoltaics (OPVs), thin-film solar cells, and
dye-sensitized solar cells (D-SSCs). Among them, the sensitized solar cells
have unique device architecture of that is consisted of electron conductors,
sensitizers, and hole conductors whereas the others are np junction type.
Recently, the inorganic and organic/inorganic hybrid sensitizers have been used
as new sensitizer to replace the conventional Ru/organic dyes owing to their
unique properties such as convenient bandgap tailoring, easy charge separation,
strong absorptivity, and good stability. Here, I would like to introduce the
recent trend of organic/inorganic hybrid sensitized solar cells and share our
research activities.
